Description Geir Ove Myhr 2010-06-24 01:18:05 UTC

Forwarding a bug report from Ubuntu user Glen Ditchfield:
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/589940

This is possibly a duplicate of fdo bug #28070.

Problem: 
Laptop monitor shows boot messages but turns black when gdm/kdm is started.

It seems that the laptop monitor is connected on DP1:
DP1 connected 1366x768+0+0 (normal left inverted right x axis y axis) 309mm x 173mm
   1366x768       60.1*+   40.1  

From intel_reg_dumper: PCH_eDP_A: 0xb0854004

This is with Ubuntu 10.10 kernel 2.6.35-2.3-generic based on 2.6.35-rc2.


Original bug report:

I made a USB key and booted an HP Elitebook 8440p model WH255UT#ABA. (Chipset: Mobile Intel QM57 Express, graphics: Intel Graphics Media Accelerator HD.) I selected "Try Kubuntu without installing". The screen flashed repeatedly, then showed a blinking underscore cursor, then turned black. After some seconds I heard the KDE start-up sound, but the screen stayed black. Ctrl-Alt-F1 did nthing.

With "splash" removed from the boot options, the result was the same.

here is a new patch on the intel-gfx mailing list today that may fix this.

Should have been fixed by
https://patchwork.kernel.org/patch/108727/
which is in drm-intel-next now

Indeed. It is even in -rc4. Glen just tested an -rc4 based Ubuntu kernel and reports the problem is resolved.
